So here is a sneak peek of the fun-loving Middleton family getting into the festive spirit with William, 30, and Kate, 30, merrily joining in.

Younger sister Pippa proudly shows off her new red undies, a sexy stocking filler from a mystery admirer at Camp Bastion. Could it be from her sister’s cheeky brother-in-law Prince Harry, 28?

Meanwhile, mum Carole, 56, slips out for a sneaky ciggie and a glass of wine with one of the royal protection officers and the whole family enjoy fancy dress, party games and practical jokes.

Before a massive turkey dinner and a glimpse of the Queen’s Speech, Wills headed out for a pint and a flutter on a fruit machine at the local with his father-in-law Michael.

These lively antics behind closed doors maybe show why the Duke and Duchess of Cambridge opted to spend Christmas with the Middletons in Berkshire, rather than at Sandringham.

It is the family as you have never seen them before and probably will never see them again.

That is because it is really another clever set of spoof lookalike images, taken by Bafta-winning photographer Alison Jackson, 42.

She decided to set up the Middletons’ lively family Christmas after Pippa, 29, revealed that dad Michael, 63, turned up for the celebrations a couple of years ago in an inflatable sumo wrestler outfit.

A source revealed: “It got Alison thinking what high jinks would the Middletons get up to this year with Wills and Kate as special guests?”

Looking at the finished results, which Alison released on her Twitter page, it seems that her imagination has gone into overdrive.

One shot shows Pippa forgetting to remove the cut-price stickers from the cover of her flop book Celebrate, as she wraps up unsold copies for gifts.

It will be the last year the Middletons enjoy Christmas at the house as they are moving into a £5million mansion nearby.

Next year, all being well, William and Kate will be celebrating their first Christmas with their new baby.
